Large (21/25 count) or jumbo (16/20 count) shrimp, peeled and deveined
Good quality lump or jumbo lump crab meat
Heavy cream
Cream cheese (full-fat block)
Chicken or beef broth
Green bell pepper, finely diced

How to Cook This Pasta

Fill a large pot with water, add plenty of salt, bring to a rolling boil, and cook pasta until just al dente per package directions.
Before draining the pasta, reserve about 1 cup of starchy pasta water, then drain the pasta.
Pat shrimp dry with paper towels.
Heat 1 tablespoon butter and 1 tablespoon olive oil in a large skillet over medium-high heat.
Arrange shrimp in a single layer, lightly sprinkle with Cajun seasoning, and cook 1–2 minutes per side until pink and opaque, working in batches if needed; remove shrimp and set aside.
Reduce heat to medium and add another tablespoon each of butter and olive oil to the pan.
Add diced green bell pepper, yellow onion, and celery and sauté 5–7 minutes until softened and fragrant.
Stir in minced garlic and cook about 1 minute until fragrant.
Sprinkle in Cajun seasoning, smoked paprika, dried oregano, and cayenne (if using) and stir about 30 seconds to toast the spices.
Pour in about 1/2 cup broth to deglaze the pan, scraping up browned bits.
Whisk in softened cream cheese until smooth.
Slowly stir in heavy cream, bring to a gentle simmer, reduce heat to low, and cook 3–5 minutes until the sauce thickens slightly; season with salt and black pepper to taste.
Gently fold crab meat and reserved shrimp into the sauce, taking care to keep crab lumps intact.
Add the drained pasta to the skillet and toss to coat evenly, loosening the sauce with reserved pasta water as needed to reach the desired consistency.
Taste and adjust seasoning if necessary.
Sprinkle freshly grated Parmesan and chopped parsley or green onions over the pasta and serve immediately.

Tips for Perfect Seafood and Sauce

Want to take your Creamy Cajun Crab & Shrimp Pasta from great to unforgettable? Here are some of my tried-and-true tips:

Don’t Overcook the Seafood: Shrimp cooks super fast, and crab meat is already cooked. Cook shrimp just until it turns pink and remove it right away. Add shrimp back in at the end to keep it tender and juicy. Overcooked shrimp turns rubbery and nobody wants that in their comfort food bowl!
Reserve Pasta Water: Always save some starchy pasta water. It’s a secret weapon for thinning sauce and making it stick perfectly to your noodles.
Adjust Heat Levels: Cajun spice mixes vary, so taste as you go. Add cayenne for extra kick or dial it back if you prefer milder heat. It’s easier to add more than take it away!
Choose Quality Crab: Since crab is the star, use lump or jumbo lump for sweet, flaky chunks. It makes all the difference!
Fresh Herbs Finish It: Sprinkle chopped parsley or green onions right before serving to add a fresh, vibrant pop that cuts through the creaminess.
Serve Fresh: This dish shines best fresh from the stove with the cream sauce silky and seafood tender.
Great Side Pairings: A crisp green salad with light vinaigrette or some warm crusty bread perfectly balances and lets you soak up every last bit of sauce.
Add Extra Heat: For bold lovers, a drizzle of Tabasco or your favorite hot sauce over the top brings an awesome punch.
Try Other Meats: Want something heartier? Brown some diced beef sausage with the aromatics for a surf and turf vibe. Just cook it well before adding veggies.

Ways to Switch It Up

Need some ideas to switch up your cajun crab and shrimp pasta while keeping the essence? Here are a few easy options:

Protein Swaps: Replace shrimp with cooked crawfish tails or swap lump crab for claw meat for a budget-friendly twist. Add cooked andouille or smoked sausage for a meaty surf-and-turf flavor.
Pasta & Grain Options: Stick with fettuccine, linguine, or rigatoni, but penne or rotini work great too. For gluten-free, choose a quality GF option and just watch the cook time.
Spice Level: Use a mild Cajun seasoning or cut back on cayenne for less heat. Want more? Add cayenne, red pepper flakes, or finish with hot sauce.
Dairy Changes: Heavy cream and cream cheese create that signature sauce texture. For a lighter version, try half-and-half plus a bit more cream cheese, but expect a thinner, less luxurious sauce.
Non-Seafood Option: Swap seafood for hearty mushrooms, roasted cauliflower, or smoked tofu with vegetable broth for a tasty vegetarian take.
Brighten the Flavor: Try a touch of lemon zest or a squeeze of lemon juice at the end. You can also use a splash of dry white wine when deglazing for extra depth.

How to Store and Reheat

This Creamy Cajun Crab & Shrimp Pasta is best enjoyed fresh, but if you have leftovers (rare around here!), here’s how to keep it tasting great:

Refrigerate: Cool your leftovers to room temp within a couple hours, then store in an airtight container in the fridge for 2–3 days max. After that, the seafood and creamy sauce start to lose their best texture and flavor.
Reheat Tips: Cream sauces and seafood can be tricky to warm back up.
- Stovetop (My Favorite): Gently warm the pasta over medium-low heat in a skillet, adding a splash of broth or a little heavy cream to loosen the sauce and revive its creaminess. Stir carefully and avoid boiling to prevent sauce splitting or tough seafood.
- Microwave: Handy but watch out for drying out seafood or breaking the sauce. Heat in short bursts with a bit of liquid added, stirring between intervals.
Remember, reheated pasta might absorb some sauce, and shrimp can lose a bit of tender texture.
Freezing: I don’t recommend freezing this dish. Cream sauces tend to separate and get grainy, and seafood gets mushy or rubbery after thawing. If you must, expect a texture change and enjoy it soon after thawing.

Answers to Common Questions

Can I use frozen shrimp and crab?

Absolutely! Just thaw them in the fridge or under cold running water and pat them thoroughly dry. Dry shrimp sears better and won’t make your sauce watery.
Is imitation crab okay to use?

You can, but imitation crab is softer and milder in flavor. It works in the sauce but won’t have the sweet, flaky texture and taste of real lump or jumbo lump crab.
Can I make this ahead of time?

Sort of! You can make the sauce (without shrimp and crab) up to 24 hours ahead and chill it. Reheat gently and add seafood and pasta right before serving to keep seafood tender.
How do I avoid sauce breaking or graininess?

Keep the sauce at a low simmer, not boiling. When reheating, warm slowly with a splash of broth or reserved pasta water and gently whisk or stir while the cream cheese melts.
How can I reduce salt or spice?

Use low-sodium broth, cut back or skip added salt, and pick a mild Cajun seasoning or reduce cayenne. Taste and adjust as you go.
What’s the best way to reheat leftovers?

Stovetop reheating with a little broth or cream added is best to keep sauce creamy and seafood tender. The microwave works but can dry out the seafood and break the sauce.
Can I freeze this pasta?

It’s not recommended due to texture changes. If freezing, expect the sauce to separate and the seafood to get mushy when thawed.
How do I keep crab lumps intact in the sauce?

Gently fold in the crab at the last step to warm through without stirring too much. Use picked-over lump crab to avoid broken pieces.
